Cleveland Browns tight end Kellen Winslow will undergo surgery on his knee this off-season, he told WKNR AM/850 from Phoenix on Friday.

A first alternate to the Pro Bowl, Winslow postponed the surgery in hopes of going to the NFL's all-star game in Honolulu next week. When Chargers tight end Antonio Gates (dislocated toe) failed to opt out of the game by Wednesday's deadline, Winslow's hopes for making it this season were dashed.

"I'm definitely going to have a surgery done on my knee," Winslow said in an interview with Mark "Munch" Bishop. "My shoulder might be strong enough . . . I'm just really worried about my knee. Your legs are your life. I need my knee."
